Purpose & User

The Sisyphy Saiteng MMUC mouse jiggler prevents a computer from entering sleep mode during long downloads, video streams or online meetings. It suits office workers, remote staff and anyone who cannot change system power settings on a locked-down PC. Buyers who need extra storage or a second graphics card will not find that function here.

Installation & Common Issues

The device plugs into a USB-C port and is recognised immediately as a standard optical mouse, requiring no driver installation or software setup. An onboard switch toggles power with a four-second hold and cycles through three movement modes with a short press. The only typical issue occurs on systems that block all mouse-class devices, which will prevent the jiggler from functioning.

Sustained-Load Behaviour

During continuous operation the unit draws minimal power and produces no audible noise, running indefinitely without overheating. Its memory function restores the last selected track mode automatically after a reboot or when the device is re-plugged. The three programmed patterns — small-range movement, large-range sliding and subtle jitter — continue to simulate natural cursor activity for as long as the switch remains active.

Questions about this item

How do I verify the MMUC mouse jiggler is active after plugging it into my USB-C port?

The device is recognised as a USB optical mouse; the on‑board LED shows the selected track — small‑range movement, large‑range sliding or subtle jitter — confirming it is keeping the screen awake.

What comes with the MMUC and what must I supply myself?

The package contains the USB‑C mouse jiggler unit only; no cables, adapters or software are included, and no extra purchase is required for basic operation.

Which track mode should I choose on the MMUC for a typical office laptop?

Short‑press the switch to cycle through the three modes — small‑range pointer movement, large‑range sliding, or subtle jitter — and pick the one that matches your screen‑timeout settings.
